Noah reads the problem, “Evaluate each expression, giving the answer in scientific notation.” The first problem part is: 5.4⋅10^{5}+2.3⋅10^{4}. Noah says, “I can rewrite 5.4⋅10^{5} as 54⋅10^{4}. Now I can add the numbers: 54⋅10^{4}+2.3⋅10^{4}-56.3⋅10^{4}.” Do you agree with Noah’s solution to the problem?

• Yes, I agree with Noahs solution.
• No, I no not agree with Noahs solution.
